Billionaires are just like you and me—except they have no financial worries whatsoever. If they get a hankering for a vacation they can just get on their plane–frequently their very own private plane–and takeoff for destinations unknown and unimaginable. But billionaires, just like us, have lives that are funny, complicated, and dramatic—sometimes all three. They have hobbies that are bizarre. They have families. They have causes near and dear to their hearts and the money to throw at those causes to affect greater change or influence outcomes in politics.Having billions carries with it a certain amount of power, and the way it is used is as varied as are the 1,645 billionaires in the world today.
